An air filtration assembly including a filter and an air duct. The air duct defines an inlet, an outlet and passageway extending therebetween. The air duct further defines a filter-receiving portion for receiving the filter between the inlet and the outlet. The filter-receiving portion includes a filter-retaining surface extending substantially radially inwardly into the passageway. The filter-receiving portion includes a filter-securing assembly for securing the filter against the filter retaining surface. The filter-securing assembly is selectively operable between a non-retaining configuration and a retaining configuration. In the non-retaining configuration, the filter is removable from the filter-receiving portion. In the retaining configuration, the filter is secured against the filter-retaining surface through the filter-securing assembly engaging at least in part the filter so as to bias the filter towards the filter-retaining surface.
Un ensemble de filtration d'air comprenant un filtre et un conduit d'air. Le conduit d'air délimite l'admission, la sortie et le canal entre ceux-ci. Le conduit d'air délimite également une partie où se situe le filtre entre l'admission et la sortie. La partie où se situe le filtre comprend une surface de retenue du filtre qui s'étend radialement dans le canal. La partie où se trouve le filtre comprend un ensemble de fixation du filtre afin de fixer le filtre contre la surface de fixation du filtre. L'ensemble de fixation du filtre s'utilise avec une configuration de non-fixation et une configuration de fixation. Avec la configuration de non-fixation, le filtre est amovible de la partie où se situe le filtre. Avec la configuration de fixation, le filtre est fixé contre la surface de fixation du filtre grâce à l'ensemble de fixation du filtre en prise avec au moins une partie du filtre de façon à incliner le filtre vers la surface de retenue du filtre.
